I say, do whatever makes you happy. I figure: it's hair. It grows back. Shorter cuts require more frequent visits to the salon, though. So, to maintenance will, in essence, cost more. (if cost is an issue at all for you - it is for me. ) You just have to figure out if it's really what you want or not.

As a side note, let me say that I ALWAYS had a crown that didn't curl as much as the rest of my hair.... that is, until I had been CG for a while. Once I got on the CG bandwagon, fully, the top that never really curled much before started curling. That could happen to you, too. ...Just sayin'. Good luck!
